摘要：
A method for co-channel interference suppression in Orthogonal Frequency Division Multiplexing (OFDM) systems with multiple receiving antennas is provided, wherein the co-channel interference (CCI) in different directions is suppressed by the spatial technique provided by the antenna arrays, and the interference to a desired carrier caused by other sub-carriers is also taken into consideration, that is, the interference of other sub-carriers is cancelled by means of a multistage interference cancellation, thereby the performance for interference suppression is improved.
